dirstate-v2: Move fixed-size tree metadata into the docket file
Before this changeset, the dirstate-v2 data file contained not only nodes
and paths that may be reused when appending to an existing file,
but also some fixed-size metadata that applies to the entire tree
and was added at the end of the data file for every append.
This moves that metadata into the docket file, so that repeated "append"
operations without meaningful changes don’t actually need to grow any file.

Testing recorded "modified" files for merge commit ================================================== This file shows what hg says are "modified" files for a merge commit (hg log -T {files}), somewhat exhaustively. This file test multiple corner case. For merges that involve files contents changing, check test-merge-combination-file-content.t For merges that involve executable bit changing, check test-merge-combination-exec-bytes.t Case with multiple or zero merge ancestors, copies/renames, and identical file contents with different filelog revisions are not currently covered. $ . $TESTDIR/testlib/merge-combination-util.sh Files modified or cleanly merged, with no greatest common ancestors: $ hg init repo; cd repo $ touch a0 b0; hg commit -qAm 0 $ hg up -qr null; touch a1 b1; hg commit -qAm 1 $ hg merge -qr 0; rm b*; hg commit -qAm 2 $ hg log -r . -T '{files}\n' b0 b1 $ cd ../ $ rm -rf repo A few cases of criss-cross merges involving deletions (listing all such merges is probably too much). Both gcas contain $files, so we expect the final merge to behave like a merge with a single gca containing $files. $ hg init repo; cd repo $ files="c1 u1 c2 u2" $ touch $files; hg commit -qAm '0 root' $ for f in $files; do echo f > $f; done; hg commit -qAm '1 gca1' $ hg up -qr0; hg revert -qr 1 --all; hg commit -qAm '2 gca2' $ hg up -qr 1; hg merge -qr 2; rm *1; hg commit -qAm '3 p1' $ hg up -qr 2; hg merge -qr 1; rm *2; hg commit -qAm '4 p2' $ hg merge -qr 3; echo f > u1; echo f > u2; rm -f c1 c2 $ hg commit -qAm '5 merge with two gcas' $ hg log -r . -T '{files}\n' # expecting u1 u2 $ cd ../ $ rm -rf repo
